centrality

Low-level internals. This section documents the Rust-backed structures and functions that power cityseer. They are provided for reference. For analysis, use the higher-level wrappers instead: the CityNetwork class, or the metrics and tools modules. Symbols on these pages are not part of the public API and may change between releases without a deprecation cycle.
